Communication between FS filter and USB WMD driver.

Hi all,
Here is a case:
I have a FS filter driver and an USB WDM driver, both of them launching on Windows XP. Is there any way that they can talk each other? Thanks for any help.

You can either setup entry points in the device extension and call
directly between them. Or you can call via IOCtls using IOCallDriver().
Or using an interface GUID mechanism as in the toaster example.

PnP device interface and device interface arrival notification can help.
